From Destinypedia, the Destiny wiki
Eao was an Ahamkara who lived among the Awoken of the Dreaming City. He was known for his love of story-telling and his knowledge of Awoken legends and history. However, he betrayed the Awoken by leaving the Dreaming City and threatening to reveal the secrets of the Awoken to the Warlocks of the Last City. Sjur Eido hunted Eao down and slew him, but a Warlock managed to purchase his remains and sell his bones. His bones were later made into the Hunter boots known as the Bones of Eao.
